| Hello all, I am simply trying to solve Laplaces equation inside a Ball[] but I receive a strange error message talking about the PDE coefficient not evaluating to a numeric matrix of dimension of {3,3,3} at the origin. Any help would be... |
| Thanks! The answer on that page does not fully make sense to me but it will be enough to figure out how to move forwards! |
| Hi all, I am trying to find a numerical solution to Laplaces equation in spherical coordinates. My geometry is an interesting one which is a ball with a cone removed out of the center of it. I want the outside surface of the ball to be at one... |
| Hi all, I am trying to learn the new FEM package in Mathematica and am having trouble implementing the Boundary Conditions. My example problem is just a cube with one face in the z direction being at T=100 and the other z direction face at T=0... |
